Ubuntu: Which is the best PDF metadata viewer for Ubuntu?



Question:

There are a lot of questions and answers regarding the best PDF viewer available with Ubuntu. But I want to parse the PDF file and know details of PDF, such as images, fonts and links that are available in a given PDF file.

Are there any PDF metadata viewers available?


Solution:1

  1. View pdf metadata for a file called Example.pdf:

    pdfinfo Example.pdf    
  2. Edit existing metadata in the terminal using nano editor:

    pdftk Example.pdf dump_data output Metadata-output.txt  nano Metadata-output.txt    
  3. Update metadata:

    pdftk Example.pdf update_info Metadata-output.txt output Example-new.pdf  

Nano editor keyboard shortcuts
Use the keyboard combination Ctrl + O and after that press Enter to save the file to its current location.
Use the keyboard combination Ctrl + X to exit nano.

CLI solution

Another utility worth looking into is exiftool. The advantage exiftool holds over pdfinfo is that it supports a lot more metadata types (e.g. XMP tags).

Here's an example of a command that will print all available meta information (-a), sorted by groups (-G1):

exiftool -a -G1 "$File"  

Overviews of the supported PDF-related tags:

You can install exiftool on Ubuntu with:

sudo apt-get install libimage-exiftool-perl  

GUI solution

If you are looking for a GUI PDF metadata viewer/editor you could give PDFMtEd a try. It's a a set of graphical utilities I wrote for managing PDF metadata with exiftool:

Solution:3

The answer of "best" really depends on how much detail you want and on how stable you want the viewer to be. There exists many softwares for viewing and even editing post script and pdf files in linux; all which seem to have been removed from the current Ubuntu repositories (probably due to stability issues).

For now I'd recommend trying pdfedit. If you are using Quantal or earlier it can be installed via

sudo apt-get install pdfedit  

For newer releases you'll need to download it from it's project page, unpack it, and compile it your self.
